I've seen this before. Well I haven't but Ienzo has. He remembers the felling of content that a child has while in its mother's arms. It does not move it never stirs only feels the presence of its mother. Another thought never enters its mind the only important thing is the warmth of its mother.
Ienzo never had that. It was one of the many things he envied about the children he saw playing in the villa. They were so happy so carefree the world had no effect on them. They had family friends and again no cares they could not comprehend anything other than their foolish games. Oh, but how Ienzo longed to play those games; to feel accepted and cared for.
As Zexion stared at the strong arm that twisted around his waist and held him to the warm body behind him he couldn't help but think of Ienzo's past. It was a horrible burden for him to see a body that resembled him so much so through such pain. It was Ienzo's pain but he could feel it. No mater how much Xemnas said they could not feel Zex
